Hi
If anyone have tried MPLS on OVS successfully, please check if the following
syntax to push/pop is correct.
The reason I ask: I am trying Simon's code base that has MPLS datapth support.
After adding these flows, I could not see packets going out with labels. The
log -vswittchd.log has error msg "Invalid arguement" while pushing or poping
the labels. ( see below the error msg)
I wonder if I miss something obivious in the commands.
Thanks in advance
